[HouseCalls]

Preflop - good
Flop - good

If MP1 is a reasonable player I would put him on AJ, KJ, QJ or JT calling down with top pair but afraid you have top pair with better kicker or an overpair given your preflop raise. The other possibility is a heart flush draw though a TAG might go for a free card play in that spot.

Turn - Based on above a check here might give you some info; if he bets he probably has a J if he checks he's more likely on the flush draw.

River - as played against a TAG I c/c to avoid possible raise. I don't think the bet will make him fold if he has a J and he will fold if he missed the flush so it has no value. (Against the typical low limit LP-P The value bet here may be worth it)
