Hello Sir,
Yep, I think we can do that, however I think it's pointless, since checking 100% of our range is a) really close to optimal, b) keeps our range together, c) far easier to do than anything else (=> maximizing hourly, not EV).
My main reason is the following:
Board: Q♦J♥8♥ A♠
Equity Win Tie
MP2 46.86% 45.27% 1.60% { our c/r range - see above }
MP3 53.14% 51.54% 1.60% { 88+, A7s+, K9s+, QTs+, JTs, T9s, 98s, A9o+, KTo+, QJo }
Also our opponent can easily raise any A in this spot, that is a good majority of his range. We don't have an uncapped range, since we have KT, T9, AA, QQ, JJ, so that's not a prototypical spot for donkchecking 100%, but I still think it's the best play given we'll get raised an awful lot, and honestly, I'd want to fold much more than optimal because of his perceived preflop range being so nutty on this board. Another thing to consider: will we have enough bluffs given that KT came in that was 16 combos from our 62 combo bluffing range (we also need c/r bluffs), etc.
So I think checking 100% here should be good, if not the best, it's really close, and if we have these kind of standard plays, we can add a couple tables more to maximize hourly. But if you have any suggestion or idea why we should still have a betting range here, I'm curious, so let me know.
