The provided pre-match odds comparison data reveals significant divergences between sharp and soft bookmakers across several secondary markets, specifically Total Corners (1st Half) and Cards Asian Handicap. The most pronounced discrepancies are observed in 'Total Corners (1st Half) Under 4', showing an EV of +36.7% against Marathonbet, and 'Cards Asian Handicap Away +0' with an EV of +35.42% against Bet365. These values, while high, suggest a potential mispricing in the soft market that has not yet converged with the sharp bookmaker's assessment.

However, the core 'Lineup Info Edge' strategy relies on identifying alpha generated by unexpected lineup changes that haven't been priced into the market. As the current data is pre-lineup announcement, these high EV percentages likely reflect either inherent inefficiencies in soft bookmaker pricing for these less liquid markets or a pre-existing information asymmetry not yet related to specific player news. Without the context of actual lineup changes and their impact on team strength, particularly in offensive or defensive capabilities that influence corners or card accumulation, these EV figures are speculative and do not yet constitute a confirmed 'lineup edge'.

1. Identify Strategy Focus: The 'Lineup Info Edge' strategy targets market inefficiencies arising from unexpected player news (benchings/injuries) post-lineup announcement.
2. Review Provided Data: The data shows significant EV in corner and card markets, with sharp vs. soft bookmaker divergences up to +36.7%.
3. Assess Lineup Impact: The prompt states 'Monitoring for lineup announcement impact', indicating the current data is before any specific lineup news has been factored in by the market.
4. Evaluate EV Context: While the EV figures are high, they are not yet attributable to a 'lineup edge' as no specific lineup information has been provided or analyzed. These divergences could be due to general soft bookmaker inefficiency or other factors.
5. Determine Signal Type: Given the high EV figures but the absence of the critical lineup information required by the strategy, the appropriate signal is an 'alert'. This signifies a market area of interest with potential alpha, but requires further information (lineup news) to confirm a actionable 'back' signal.
6. Set Confidence and Strength: Confidence is set to 'medium' because the high EV divergence is notable, but not 'high' or 'extreme' as the core trigger (lineup news) is missing. Strength is set to 65, reflecting the significant price discrepancy but also the conditional nature of the signal.
7. Select Market/Selection: The 'Total Corners (1st Half) Under 4' market offers the highest observed EV, making it the primary focus for an alert.
