Maybe a Straight Flush?

Grzegorz Kozieja opened in middle position to 55,000. It folded to Gaelle Baumann on the button who called before Hwany Lee defended his big blind.

The 10♦5♦4♦ flop hit the felt and action quickly checked through to an 8♦ turn. It checked to Kozieja who put out a delayed continuation-bet of 50,000. Both of his opponents called.

The 6♦ landed on the river and Lee went into the tank for a moment before gathering enough chips to put in a large over-bet to the tune of 525,000.

Both of his opponents sat in the tank for almost two minutes each but eventually they both found a fold. Could Lee lead for this sizing with anything other than a straight flush?
