[Q..]

Hmm well UTG calls t60 (pot was t90), Hero raises to t270 i called this a reraise but nethermind, as about protection no - no protection here, just betting for value, on the flop no bet is called by worse hand, on the turn there are hands that will-might call which we have beat.

Also double check - he probably didn't call with A to check it twice, happens of course but less likely then smth different.
